摘要： Impact-damage-resistant glass sheet comprising at least one chemically etched surface in combination with a tempering surface compression layer, the glass sheet exhibiting a high standardized ball drop failure height and a high flexural modulus of rupture strength, useful to provide damage-resistant glass cover sheets for consumer electronic video display devices, is provided by subjecting thin glass sheet to a combination of a surface tempering treatment and a surface etching treatment that improves strength while maintaining the optical glass sheet properties required for video display applications.

摘要： The present invention relates to a method for etching a primary preform, the method comprising the steps of: * introducing the primary preform having an outer diameter OD PP into the central cavity of a hollow etching tube having an outer diameter OD ET and an inner diameter ID ET such that in angular direction a part of the outer surface of the primary preform contacts a part of the inner surface of the etching tube, thereby forming an open region between a remaining part of the outer surface of the primary preform and a remaining part of the inner surface of the etching tube; * mounting the etching tube with the primary preform inserted in its central longitudinal cavity on a lathe and introducing the etching tube into a central aperture of an applicator mounted on the lathe wherein the applicator and the etching tube are moved in axial direction with respect to each other; * rotating the etching tube around its axis thereby causing a counter rotation of the primary preform within the etching tube; and * coupling electromagnetic radiation into the applicator and creating within a part of the etching tube that is surrounded by the applicator a plasma that moves in translation back and forth over the length of the etching tube during one or more passes wherein during at least a part of at least one pass the outside of the primary preform is etched by supplying a fluorine-containing etching gas to the open region in order to obtain an etched primary preform. The present invention moreover leads to a preform and optical fibers obtained therefrom.

摘要： An atmospheric, Laser-based Chemical Vapor Deposition (LCVD) technique provides highly localized deposition of material to mitigate damage sites on an optical component. The same laser beam can be used to deposit material as well as for in-situ annealing of the deposited material. The net result of the LCVD process is in-filling and planarization of a treated site, which produces optically more damage resistant surfaces. Several deposition and annealing steps can be interleaved during a single cycle for more precise control on amount of deposited material as well as for increasing the damage threshold for the deposited material.

摘要： To provide cover glass for mobile terminals exhibiting high strength in a thin plate thickness state to enable reductions in thickness of apparatuses when inserted in the apparatuses, cover glass (1) for a mobile terminal of the invention is cover glass (1) that is obtained by forming a resist pattern on main surfaces of a plate-shaped glass substrate, then etching the glass substrate with an etchant using the resist pattern as a mask, and thereby cutting the glass substrate into a desired shape and that protects a display screen of the mobile terminal, where an edge face of the cover glass (1) is formed of a molten glass surface, and as surface roughness of the edge face, arithmetic mean roughness Ra is 10 nm or less.
